Hello ! I'm a PC player on Microsoft (game pass). I played yesterday, and everyting was working well. Today, I launch the game and when I move my mouse - the camera - the FPS suddenly drop. But only when I move the camera, for example if I juste move forward there is no problem. My PC didn't made any updates (nvidia, lghub for my mouse, grounded, etc.). Any idea ? Thanks !
